I know a number of people have trouble using dark themes with Ubuntu because the software center likes to keep its white background and also use the default light colored text. The following solution is pretty hack-tastic and I'm hoping to hear some more elegant ideas.
1) Open up a terminal and type:
2) The first two lines should look like this:Code:gksudo gedit /usr/share/software-center/ui/gtk3/css/softwarecenter.css
Copy and paste those two lines right below then comment out the originals. Change the two HTML color codes (#DED7DB and #F4F1F3) to your preferred dark colors so that light text will show up.Code:@define-color light-aubergine #DED7DB; @define-color super-light-aubergine #F4F1F3;
3) Save and close gedit. Launch Ubuntu Software Center to check out the results
